What we have thought about

Nature offers us potent substances - for example, polyphenols. A polyphenol-rich diet (e.g. walnuts, green tea, green vegetables, blueberries, etc.) can also have a positive effect on our metabolism and immune system.

A subgroup of polyphenols are the so-called flavonoids, which are yellow plant pigments produced by the plant to protect it or its flowers and leaves from harmful influences. 

Our preparation combines 4 different flavonoids to achieve optimal effect: quercetin, rutin, luteolin and genistein.

The whole is supplemented by PEA (palmitoylethanolamide). This is a fatty acid amide. 

It is important to know that the botanicals used are not useful for people with salicylate intolerance.

You probably already know that vitamin D is important for our bones and sufficient calcium absorption from the intestines. Less known is the particularly balancing role of vitamin D in the immune system: without sufficient vitamin D in the body, mast cells activate "automatically". Thus, vitamin D contributes to the normal functioning of the immune system.

Mast cells are white blood cells located in the tissues of our body. In the mast cells there are numerous small granules filled with messenger substances - e.g. histamine, heparin, prostaglandins etc.. When a mast cell is activated, the so-called degranulation occurs, which means that the stored messenger substances (approx. 200 different ones) are released.

Food supplements

What else can I do for a good immune system?

The basic prerequisite is, of course, that you give your body all the nutrients it needs - especially the proteins and essential amino acids as well as the anti-inflammatory omega-3 fatty acids (mainly found in fatty fish) are particularly important building blocks for many enzymes and new cells. So try to eat as balanced and varied a diet as possible - especially unprocessed foods, lots of vegetables, grains, nuts and seeds. This also supports the development of a healthy intestinal flora - and health often starts in the intestine!

Try to avoid alcohol as much as possible - it can have an immunosuppressive effect and changes your gut flora.

Often our immune system gets out of balance when our body is stressed - this can be a mental strain, physical overload or an infection. It is not always possible to quickly change this stress. Breathing exercises and yoga as well as endurance sports can help reduce the body's stress response. Regular breaks and downtime are just as important - try setting your mobile phone alarm every 1-2h, getting up from your desk and taking a few steps.

Many patients with mast cell activation syndrome can additionally pay attention to mast cell liberators in their diet. The following list gives you an overview:

Recommended intake / dosage

Take 2 capsules with 200 ml of water twice daily with food or with a little oil.

In rare cases, flavonoids may cause nausea or constipation. PEA can have a vasodilatory effect.

It is not recommended to be taken in case of salicylate intolerance.

As there are no studies on use during pregnancy, breastfeeding or in children, we recommend taking it in these cases only after consulting a doctor.

Our quality promise

Our capsules are made of HPMC (hydroxypropylmethylcellulose) - i.e. vegetable cellulose and do not contain any potentially harmful substances such as PEG (polyethylene glycol) or carrageenan.

All ingredients are tested in an HACCP- and GMP-certified plant in Austria according to the quality standards valid in the EU and are also encapsulated here.

We do not use any potentially harmful release agents or superplasticisers such as titanium dioxide or silicon dioxide; if necessary, we use microcrystalline cellulose as a filler.

All our products are GMO-free, gluten-free and lactose-free. All products are also suitable for a vegan diet.
